Tom Watson commented on FELIX-6552:
-----------------------------------
An error should have been logged with the LogService, but the service component
must not be prevented from being activated according to the specification:
https://docs.osgi.org/specification/osgi.cmpn/8.0.0/service.component.html#service.component-binding.services
> In case of class-cast exception, a component is still activated
> ---------------------------------------------------------------

> Key: FELIX-6552
> URL: https://issues.apache.org/jira/browse/FELIX-6552
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Reporter: Christoph Läubrich
> Priority: Major
>
> I recently found a very strange behavior with one of my components:
> # there is a static bound setter for a service X
> # in case of injection of X I call a method an perform some action on it
> # if it now happens that a ClassCastException is thrown this seems to be
> silently ignored
> # my activate method is called and the service seems to be registered
> sucessfully
> This is very bad, because I only noticed that something was wrong because it
> failed then later on and everything looks "normal" (no entry in the OSGi log
> for example, component seems to be activated...)
